Characterization of Boundary Layer Tripping and Vortex Shedding Mitigation Techniques on Flow over a Circular Cylinder
Flow over a circular cylinder has been extensively studied in the past due to its many practical applications. Examples include flow around bridge suspension wires, architectural structures, and aircraft landing gear components. When examining a particular application, the flow must be carried out at a specified flow regime to ensure comparable and reliable results. Flow regimes for a circular cylinder are commonly defined in terms of two primary non-dimensional parameters based on cylinder diameter: the Reynolds number, which represents the ratio of inertial to viscous forces, and the Strouhal number, which represents the ratio of a periodic velocity to a freestream velocity condition. In an experimental wind tunnel setting, several physical constraints limit the flow regimes that can be achieved, such as maximum allowable tunnel blockage and the range of possible flow speeds. Hence, to achieve a desired flow regime for a high Reynolds number application, techniques to alter the fluid flow such as boundary layer tripping may need to be performed to generate the characteristic flow features indicative of the desired regime. In addition, for the future application of these techniques to more complex geometries, the mitigation of vortex shedding from a particular region may be desired to better isolate the acoustic contribution of another region of interest on the geometry. The goal of this project is to characterize the effect of boundary layer tripping and vortex shedding mitigation techniques for flow over a circular cylinder. Measurement methods may include steady and unsteady surface pressure measurements and Laser Doppler Velocimetry (LDV) measurements in the wake of the cylinder. The surface pressures and wakes of the cylinder will be compared for the following cases: flow over a cylinder, flow over a cylinder with boundary layer tripping, and flow over a cylinder with boundary layer tripping and vortex shedding mitigation.
